Hideki "Rusian" Nishimura was brave enough to propose to a girl in an online game, only to be rejected by her. To make matters worse, he discovered that she was actually an older man in real life. Feeling betrayed and heartbroken, Rusian made the decision never to trust another girl in an online game again. Years later, Rusian joined a guild with three other players, one of whom had a female avatar named "Ako." Ako fell deeply in love with Rusian and wanted to marry him. Although he considered the possibility that she might be male, Rusian agreed to her proposal because he believed that cuteness mattered more than gender in the game. However, after a discussion between guild members led to an offline meeting, Rusian learned that Ako and the other players were not just girls but also his schoolmates.
